Dural arteriovenous malformation with abnormal parenchymal vessels: an autopsy study.
A 48-year-old man with dural arteriovenous malformation (AVM) is reported. Radiologically, the dural AVM was demonstrated mainly in the region of the left transverse sinus. Postmortem examination revealed dural AVM involving the bilateral transverse, superior sagittal and straight sinuses. In addition, numerous malformed venous vessels and extensive necrosis were observed mainly in the parenchyma of the brain stem and cerebellum. The present case suggests that dural AVMs may be associated with malformed venous vessels in the brain parenchyma.
